    (Sorry but my English is not good)
    Hi, I want to do an inverter and I dont know how. My idea is create a sine wave (with pic or opamp) and then amplify it and put it in a transf. and using a battery to obtain the necessary current to the load.
    I hope you can help me with this project and if my idea is wrong I appreciate if you give me other ideas. Thanks.

    Hello zodiakoko

    Your idea is good. So they are, more or less, as commercial inverters. just in the same amplifier include the oscillator.

    Missing a detail in your approach:
    How much current must provide the inverter?
    Or how many Watts is the device connected to the inverter?

    If this device demands a power of 10 Watts, this same power, more losses, the battery should be able to provide.

    Sometimes it is easier to purchase an inverter already done.

    Thanks inwo, but I'm looking for a more complex circuit (not very complex >.<) Is for my project in the university. I appreciate your cooperation.
    I mean if is possible to create a sine wave with pic or oscillator (5Vpp) then I need to amplify it? And if is yes, how and how much? After that I'll put the signal in the input of a transf. to obtain 220V and I'll use the battery just to obtain the necessary current.
    If my idea is correct,what is the circuit to amplify the sine wave before to introduce in the input transf.? If not give more ideas. Thanks again.

    Its theoretically possible to make and amplify a sine wave, but that would be terribly inefficient. Good sine wave inverters use PWM to create the sine wave.

    Brownout, do you have any circuit about this kind of inverter (using PWM)?
